Federal Aviation Administration

14 CFR Part 39

[Docket No. FAA-2012-0772; Directorate Identifier 2007-SW-053-AD; 
Amendment 39-17393; AD 2013-05-21]
RIN 2120-AA64


Airworthiness Directives; Eurocopter France Helicopters

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: We are adopting a new airworthiness directive (AD) for 
Eurocopter France (Eurocopter) Model EC130 B4 helicopters with a cabin 
vibration damper installed. This AD requires installing a vibration 
damper casing assembly on both sides of the helicopter. This AD was 
prompted by a crack and failure of a cabin vibration damper blade. The 
actions of this AD are intended to modify the cabin vibration damper 
assembly to prevent contact with the flight controls in the event of a 
cabin vibration blade failure, jamming of a flight control, and 
subsequent loss of control of the helicopter.

DATES: This AD is effective April 30, 2013.
    The Director of the Federal Register approved the incorporation by 
reference of a certain document listed in this AD as of April 30, 2013.

ADDRESSES: For service information identified in this AD, contact 
American Eurocopter Corporation, 2701 N. Forum Drive, Grand Prairie, 
Texas 75052; telephone (972) 641-0000 or (800) 232-0323; fax (972) 641-

referenced service information at the FAA, Office of the Regional 
Counsel, Southwest Region, 2601 Meacham Blvd., Room 663, Fort Worth,

SUPPLEMENTARY INFORMATION:

Discussion

    On July 26, 2012, at 77 FR 43738, the Federal Register published 
our notice of proposed rulemaking (NPRM), which proposed to amend 14 
CFR part 39 to include an AD that would apply to Eurocopter Model EC130 
B4 helicopters with a cabin vibration damper installed, except those 
modified in accordance with Modification 073565. That NPRM proposed to 
require installing a vibration damper casing assembly on both sides of 
the helicopter. The proposed requirements were intended to prevent 
contact with the flight controls in the event of a cabin vibration 
blade failure, jamming of a flight control, and subsequent loss of 
control of the helicopter.
    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Union, issued EASA AD No. 
2006-0278, dated September 7, 2006 (AD 2006-0278), to correct an unsafe 
condition for the Eurocopter Model EC130 B4 helicopter. EASA advises of 
a cracked cabin vibration damper blade, which could lead to jamming of 
a flight control.

Comments

    We gave the public the opportunity to participate in developing 
this AD, but we did not receive any comments on the NPRM (77 FR 43738, 
July 26, 2012).

FAA's Determination

    This helicopter has been approved by the aviation authority of 
France and is approved for operation in the United States. Pursuant to 
our bilateral agreement with France, EASA, its technical 
representative, has notified us of the unsafe condition described in 
the EASA AD. We are issuing this AD because we evaluated all 
information provided by EASA and determined the unsafe condition exists 
and is likely to exist or develop on other helicopters of this same 
type design and that air safety and the public interest require 
adopting the AD requirements as proposed.

Differences Between This AD and the EASA AD

    The EASA AD requires two daily visual inspections for cracks in the 
blade of each cabin vibration damper and replacement of a blade if 
there is a crack; this AD does not. The EASA AD requires compliance by 
a calendar date. This AD requires compliance within 100 hours time-in-
service.

Related Service Information

    Eurocopter has issued Alert Service Bulletin (ASB) No. 53A008, 
Revision 0, dated July 19, 2006 (ASB 53A008), which supersedes ASB No. 
05A002, Revision 0, dated July 18, 2006, and specifies installing a 
cabin vibration damper containment device. EASA classified ASB 53A008 
as mandatory and issued AD 2006-0278 to ensure the

[[Page 18231]]

continued airworthiness of these helicopters.

Costs of Compliance

    We estimate that this AD will affect 122 helicopters of U.S. 
Registry.
    We estimate that operators may incur the following costs in order 
to comply with this AD.
     $340 for 4 work-hours to install a vibration damper casing 
assembly at an average labor rate of $85 per work-hour,
     $1,500 for required parts per helicopter, and
     $224,480 total cost for the fleet.

Authority for This Rulemaking

    Title 49 of the United States Code specifies the FAA's authority to 
issue rules on aviation safety. Subtitle I, section 106, describes the 
authority of the FAA Administrator. Subtitle VII: Aviation Programs, 
describes in more detail the scope of the Agency's authority.
    We are issuing this rulemaking under the authority described in 
Subtitle VII, Part A, Subpart III, Section 44701: ``General 
requirements.'' Under that section, Congress charges the FAA with 
promoting safe flight of civil aircraft in air commerce by prescribing 
regulations for practices, methods, and procedures the Administrator 
finds necessary for safety in air commerce. This regulation is within 
the scope of that authority because it addresses an unsafe condition 
that is likely to exist or develop on helicopters identified in this 
rulemaking action.

Regulatory Findings

    This AD will not have federalism implications under Executive Order 
13132. This AD will not have a substantial direct effect on the States, 
on the relationship between the national government and the States, or 
on the distribution of power and responsibilities among the various 
levels of government.
    For the reasons discussed above, I certify that this AD:
    (1) Is not a ``significant regulatory action'' under Executive 
Order 12866;
    (2) Is not a ``significant rule'' under DOT Regulatory Policies and 
Procedures (44 FR 11034, February 26, 1979);
    (3) Will not affect intrastate aviation in Alaska to the extent 
that it justifies making a regulatory distinction; and
    (4) Will not have a significant economic impact, positive or 
negative, on a substantial number of small entities under the criteria 
of the Regulatory Flexibility Act.
    We prepared an economic evaluation of the estimated costs to comply 
with this AD and placed it in the AD docket.
